2 Claims.

This invention relates to improvements in veterinary medical instrument.

The principal objects of this invention are:

First, to provide a multiple purpose instrument that is extremely usefulfor treating cattle.

Second, to provide a veterinary medical instrument that is simple andinexpensive, while at the same time being extremely useful as a cattletube, medicine administering instrument, fetatome, and speculum.

Third, to provide an instrument that is easily used and manipulated, andwhich is provided with an adjustable handle for controlling theinstrument and for holding it in place.

Other objects and advantages of my invention will be apparent from aconsideration of the following description and claims.

The drawings, of which there is one sheet, illustrate a preferred formof my instrument.

Fig. 1 is a perspective view of the assembled instrument.

Fig. 2 is a fragmentary end elevational view partially broken away intransverse cross section illustrating the mounting of the crossbar onthe instrument.

Fig. 3 is a fragmentary elevational view partially in longitudinal crosssection illustrating the construction of the end of the instrument.

My instrument consists first of a tube l of relatively light weightdrawn sheet metal construction. The tube is approximately 20" long and 1A" in diameter. The length and diameter of the tube can varyconsiderably from these specific dimensions, but I have found theexample illustrated to be highly satisfactory. The lower end of the tubeshown in Fig. 1 forms the inner end of the instrument which is insertedinto a body cavity of cattle for medical or surgical purposes, and thisinner end is smoothly rounded as at 2 by turning the end of the tubeoutwardly in a smoothly rolled bead.

Along one side of the tube are formed a series of longitudinallyextending oval slots 3 which are useful in exposing the walls of thecavity through which the tube is extended for observation or surgicaloperation on the cavity walls.

Mounted on the outer end of the tube is a handle and adjusting membergenerally indicated at 4. The handle consists of a, split ring or clamp5 that fits adjustably around sitely extending handles or arms 6 and 1that project from the ring on opposite sides of the split in the ring.The handle 6 is conveniently formed integrally with the ring 5 but thehandle I is provided with an inwardly extending bolt portion 8 on itsinner end that extends through a bore in one side of the ring and into athreaded aperture 9 in the other side of the ring. The handle 1 thusforms an adjusting and clamping screw element for clamping the ring 5about the tube to secure the handle in its adjusted position.

Each of the handles is provided with a fiat eyelet Ill near its outerend adapted to receive a bit strap for holding the instrument inadjusted position on an animal. The adjustable handle 4 can the tube andoppoin 1861, pp. 293-4.

be clamped in place on the tube either before or after insertion of theinstrument into the animal, and serves as a guide for controlling thedegree of insertion. It also serves to move or adjust the tube as whenthe instrument is used as a speculum or proctoscope for inspecting thecavity in which the instrument is inserted.

In addition to the uses of the instrument already described, it may beused to protect a flexible cattle tube inserted into an animals stomach,or it may be used in place of a balling gun for the administration ofcapsules or other medicines. A small light not illustrated may bemounted in various positions in the tube to illuminate the areas exposedthrough the inner end of the tube or through the slots 3. Because of itsmany possible uses the instrument is particularly useful to veterinarydoctors and persons similarly occupied.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. A veterinary medical and surgical instrument comprising, a rigid thinwalled tube between 15" and 25" in length and between 1" and 1 indiameter, the inner end of said tube being turned outwardly in asmoothly rounded bead, one side of said tube having a longitudinallyextending slot formed therein, a split ring adjust ably mounted aroundthe outer end of said tube and having an arm extending from one side ofthe split in the ring, a second arm rotatably supported in the otherside of said ring and extend ing oppositely from said first arm, saidsecond arm having a threaded portion engageable in the first side ofsaid split ring whereby said second arm constitutes a clamping elementfor clamping said ring and said arms to said tube, and bit strap eyeletson the outer ends of said arms.

2. A veterinary medical and surgical instrument comprising, a rigid thinwalled tube, the inner end of said tube having a smoothly rounded beadtherearound, one side of said tube having a longitudinally extendingslot formed therein, a split ring adjustably mounted around the outerend of said tube and having an arm extending from one side of the ring,a second arm extending oppositely from said first arm, means on the ringfor clamping said ring and said arms to said tube, and bit strapattaching elements on the outer ends of said arms.
